Abstract

Background: The orbitofrontal cortex has been implicated as a key component in depression by several imaging studies. This study aims to examine morphometrically glial cell and neuronal density and neuronal volume in the orbitofrontal cortex of late-life major depression patients. Methods: Post mortem tissue from 13 patients with major depression and 11 matched controls was obtained and analyzed using the optical disector and nucleator methods. Results: No changes were found in glial cell, pyramidal or non-pyramidal neuron density, or in non-pyramidal and pyramidal neuron volume in the orbitofrontal cortex. Conclusions: Based on previous findings, this study suggests variability in morphological changes within the orbitofrontal cortex, as well as the prefrontal cortex as a whole.
